Children of Infinity, a real sequel to the second-best video game ever made: The Ur-Quan Masters (formerly known as Star Control II).
It's by the original creators (neither Star Control 3 nor Star Control: Origins was) and it is a direct followup to the previous game. And it's currently on Kickstarter.
The Windows/MacOS original is free on Steam, by the way, and it's in the default repository for Ubuntu and probably other versions of Linux.
Three days left and we're almost to the Console Ports goal, which would be -ahem- a massive game-changer. Just sayin'. :D
